ive just got back from an 8 week holiday and my rMBP won't connect to the Internet. I've not changed the Internet password, and my iPhone still connects to it no problem. I've tried connecting to the network, and that connects, but then when I open safari or chrome, I can't open any page. I've tried pinging Google through a terminal window and the result is " Code: cannot resolve www.google.com: Unknown host ". I've tried forgetting the network and reconnecting but that doesn't solve the problem. Can anyone recommend a solution please?
